Dear VMD users and developers,

I installed the vmdmovie plugin. However, I can not make movies.
I use linux redhet 7.2. vmd is 1.7.1. I installed ppmtompeg package
(netpbm-progs*.rpm). I can see the script is making rgb and ppm files.
However the final test.mpg is size 0! I got a null output. Please help
me. Thank you very much.
